A year ago mayor Anne Hidalgo invited the world’s best architects to ‘reinvent’ the French capital. The competition called for environmentally friendly urban designs to transform sites such as public spaces and unloved tower blocks. Kim Willsher highlights a selection of the 23 winning proposals

Clichy - Batignolles (17th arrondissement)

Winner: L’Immeuble StreamA futuristic structure built entirely of wood on the site of a former bus terminus. It will provide shared digitised workspaces for a ‘new generation of mobile workers’ and conference and hospitality areas. In a city short of green spaces, the judges were won over by the architects’ plan to plant hop plants on the facade and install a vegetable garden on the roof. Produce from the garden will be sold, cooked and prepared on site

Masséna (13th arrondissement)

Winner: Réalimenter MassénaAn abandoned train station, Masséna is a listed building constructed in 1863 and in a listed area because of its proximity to an apartment block designed by Le Corbusier. The winning design by DGT Architects transforms the current squat building into a wood-clad and plant-covered tower of several levels that will be offered to those producing and selling healthy food

Morland (4th arrondissement)

Winner: Mixité CapitaleThe Morland Building on the bank of the Seine has one of the finest views of Paris and is a flagship project in the Reinventing Paris scheme. The building currently houses various city and state services. The successful development plan was submitted by London-based architects David Chipperfield and will transform the building into a large ground floor food market, a swimming pool, gym, apartments, a hotel, offices, a creche and a youth hostel. The top floor will feature a panoramic bar and restaurant

Paris Rive Gauche (13th arrondissement)

Winner: In VivoThis 2,869 sq metre site is currently undeveloped. The plan drawn up by Paris-based Xtu Architectes features three buildings around a central space. Algo House will offer student accommodation to Sorbonne students. Plant House will contain flats and a large terrace where residents will be encouraged to grow their own food. Tree House will contain flats with individual double balconies filled with greenery

Pershing (13th arrondissement)

Winner: Mille ArbresWidely acknowledged as one of the most spectacular projects in the Reinventing Paris competition, the area is currently used as parking for coaches and spans the peripherique ringroad around Paris. Architects Sou Fujimoto have dreamt up a massive, almost fantasy glass structure surrounded by and topped with trees. The building will house flats – including social housing – offices, a community centre, two creches, a kindergarden and a play area

Pitet (17th arrondissement)

Winner: Pichet NLACurrently an ugly collection of five 1970s tower blocks, architects Nicolas Laisné Associés’ plan to construct three new buildings with 66 flats – private and social housing – each with its own outside space, homes that the designers have described as ‘liveable gardens’

Poterne des Peupliers (13th arrondissement)

Winner: NodeA triangular disused site of more than 2,000 sq metres on the edge of Paris that was abandoned after the peripherique ringroad was built. This plan includes building a funeral parlour surrounded by trees and a multi-purpose distribution centre

Sous-station Voltaire (11th arrondissement)

Winner: Etoile VoltaireThis former electricity sub-station, largely built of iron and glass, is currently used by an artists’ collective. The winning design from Olivier Palatre Architectes will preserve the historic industrial facade while transforming the building into a modern multiscreen cinema and entertainment hall
